2 Claims.

This invention relates to a supporting struc ture for air translating apparatus, and has for an object to provide an improved structure of this type.

A further object of the invention is to provide an improved adjustable support for a fan.

A still further object of the invention is to provide improved means for permitting adjustment of a support for a fan.

A still further object of the invention is to provide a structure of improved appearance for adjustably supporting a fan, which structure may be economically manufactured.

These and other objects are effected by the invention as will be apparent from the following description and claims taken in connection with the accompanying drawings forming a part of this application, in which:

Fig. 1 is a side elevation of a fan of the pedestal type embodying the invention;

Fig. 2 is a partial section taken approximately along line 11-11 of Fig. 1;

Fig. 3 is a section taken along line IIIIII of Fig. 2; and,

Fig. 4 is a section taken along line IVIV of Fig. 2.

Referring specifically to the drawings, Fig. 1 shows a pedestal or floor-mounted type of fan embodying the invention. This fan includes a motor l0, air translating blades l I driven thereby and a substantially vertical adjustable supporting column l2 having a base l3.

Conductors I4 and a plug !5 are provided for connecting the motor Ii] to a suitable source of power. The conductors M enter the base I3 and extend upwardly through the column 62 to the motor ID. These conductors are protected at those points where it is possible that the insulation may become damaged by friction against the column l2 and the base It by a spring armoring device It. This device is attached at its lower end to the base l3 and its upper end is fastened to the column lz by a bolt 11.

The column I2 includes a lower tubular member [8 having a spline 20 therein provided by the seam that forms the tube and an upper tubular member I 9 telescopically adjustable in the lower member. The members 18 and is usually have a tin or chrome or some other bright finish thereon.

A clamping device indicated generally by the reference numeral 2| is provided for clamping the members l8 and 19 of the column l2 in adjusted position. This clamping device includes a tubular metal collar 22 which surrounds a portion of both the lower tubular member 18 and the upper tubular member 19 of the column and it is fastened to the lower tubular member I8 with a set screw 23. This collar has a shoulder 24 on its inside which holds a plate or washer 25 in position on the upper end of the lower member l8 of the column. A fibre sleeve 26 is positioned between the collar 22 and the upper tubular member I9 of the column and it serves to prevent scratching or otherwise marring of the bright finish of the upper tubular member I9 by rubbing against the metal collar 22 when it is lowered into the lower tubular member I6.

This sleeve is held in position by the washer 25 and a bead or lug 21 at the upper end of the collar 22. A recess or slot 29 is provided in that portion of the collar 22 that surrounds the upper tubular member IS. A leaf spring 30 is positioned in this recess or slot 29 and a wing nut 3| is provided for applying a force to the spring 36 to force it against the sleeve 26 and clamp the upper tubular member IS in adjusted position.

Two leaf springs 33 are attached to the lower end of the upper tubular member l9 at points approximately 104 apart on the circumference of the upper tubular member by screws 34. These springs are positioned on opposite sides of the spline 29 on the inside of the lower tubular member l 8 and when the upper tubular member I9 is turned they abut against the spline 2B and prevent complete rotation of the upper tubular member, that is, they permit turning of the upper tubular member I9 through a partial revolu- While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.

What I claim is:

1. In an adjustable support for a fan including an electric motor and fan blades driven thereby, the combination of a substantially vertical column, said column including a tubular portion and a second portion telescopically adjustable in said tubular portion and rotatable therein, a collar connected to said tubular portion and surrounding a portion of said second portion, said collar having a recess therein located adjacent said second portion, a fibre member between said collar and said second portion to prevent injuring the surface of said second portion when it is adjusted, a resilient member located in said recess in said collar and bearing against said fiber member, and means for applying pressure to said resilient member to cause it to hold said second portion in adjusted position.

2. In an adjustable support for a fan including an electric motor and fan blades driven thereby, the combination of a substantially vertical column, said column including a tubular portion and a second portion telescopically adjustable in said tubular portion, a collar connected to said tubular portion and surrounding a portion of said second portion, said collar having a recess therein located adjacent said second portion, a fibre member between said collar and said second portion to prevent injuring the surface of said second portion when it is adjusted, a bowed resilient member located in said recess in said collar, and means for applying pressure to said resilient member to cause it to bear against said fibre member and hold said second portion of said column in adjusted position.
